Takes about a minute. No obligation.
Sizing a mini-split in Campbell County means working out what the system will actually run against, season after season. 79 severe weather events were recorded in Campbell County, Kentucky between 2015 and 2024. At that rate, severe weather is a standing condition rather than an occasional disruption, and a contractor who ignores it will undersize the equipment or spec components that wear faster than they should. The outdoor unit takes the direct load, so its capacity rating and mounting placement are the decisions that matter most before anything else gets priced.
The electrical panel is what decides how a mini-split installation goes in much of this county, and what a contractor finds there is not always what the equipment needs. Half the homes in Campbell County, Kentucky were built in 1972 or earlier (2020-2024 ACS 5-year). Homes of that vintage were wired to standards set long before ductless systems existed, and the service capacity already in the walls is what a contractor has to measure before any other part of the job moves forward. If the panel cannot carry the load, that gets resolved first. The unit itself follows from that answer.
The Parts of a Mini-split System and What Gets Installed
The indoor air handler mounts high on a wall inside the room and delivers conditioned air directly into that space. The outdoor unit sits on the ground or a bracket outside the house and houses the compressor and condenser coil. Together, these two units are the core of what a contractor puts in place.
A refrigerant line set runs between the indoor and outdoor units, carrying the refrigerant that makes the system work, and it passes through a small penetration in the wall. A condensate drain line also runs from the indoor unit to carry away moisture, and the system ties into a dedicated electrical circuit at the outdoor unit.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece is positioned and routed for your home.
